"من الصعب جدًا التصديق لأنه من الصعب جدًا الطاعة"

Simplified Meaning:

Believing in something or accepting an idea can be tough when acting on it is challenging. For example, imagine a doctor telling you that to stay healthy, you need to exercise every day and stop eating junk food. You know the advice is good, but it's hard to stick to it because exercising daily and giving up your favorite snacks is difficult. The harder it is to change your habits or follow the advice, the more your mind resists believing in its importance. This idea shows up in history too, like when people found it difficult to accept new scientific ideas because adopting them meant changing long-held beliefs and ways of living. To make this idea useful in life, try to recognize when you resist believing something simply because you don't want to follow the necessary steps. Understanding this can help you take the right actions even when they're hard, and over time, believing and doing what's necessary will become easier.
